You should keep DOOM as himself, but change RED to BLACK, PHOBOS to YELLOW, and BLUE to CYAN. It would give a little more variety, making it seem like there are other surviving doom squads that are waiting to meet another.

@ToP_AfroMan1171 Hey, thanks. I managed to extract the data in the VPK so it only had Francis's files on there, then made that into it's own separate mod. After realizing to put it outside of the Workshop folder (duh) I'm finally able to keep Francis as the DoomGuy while keeping everyone else unchanged. You're a big help, man.

@kylevoakes You could try extracting this addons vpk file with GCFscape. seperate all of the models and materials for francis's model (from this addon's vpk file), and put them in the common\Left 4 Dead 2\left4dead2 folder.

Anyone able to tell me how I can keep Francis as the Doomguy, but leave everyone else unaltered? I really, REALLY want to love this mod, but I don't like how it changes all my other characters into space marines. I'd like Bill to remain as Leon (RE2), and I'd like Zoey to remain as Zoey.
